Kornelis Caps & Closures, based in Steenwijk, produces plastic caps and closures for both food and non-food products. The company offers standard sizes as well as fully customized designs and specializes in sealing jars and bottles. Kornelis also invests in technologies such as IML decoration and engraving to give packaging a stronger visual impact.

During the interview, the meeting table is covered with caps in all kinds of colors and designs — a clear showcase of what the company can create. Corry Dijkstra, Sales & Marketing Team Leader, and Marco Lankau, Internal Sales Representative, explain the wide range of their product portfolio.

“Our caps and closures range from 38 to 120 mm,” Lankau says. “We offer popular wide-mouth sizes — including 66, 82, 100, 110, and 120 mm — as well as sprinkle caps in 38, 63, 82, and 85 mm, and various sauce caps. Each product can be customized — color, height, finish, type of liner, and application all define the final configuration.”

From Standard to Custom Solutions
Kornelis offers a wide range of caps and closures, from standardized models to fully customized solutions tailored to specific customer needs. Lankau highlights a recent case for oils and vinegars: “What you see here — these black caps — is a more efficient design with fewer components and lower weight. It’s a great example of how we not only respond to our customers’ needs but also actively help reduce material usage.”

A customized cap variant requires an investment but delivers a unique solution that perfectly aligns with the customer’s brand identity and functional requirements. Dijkstra adds, “Tooling sets or insert parts require lead time. Completely new, customer-specific molds take more time and cost more, but they provide years of continuity for the customer.”
